The extract below says it all . . .the video at the Democracy Now! site explains it: among other things, the countries that have liberalised most are those in which global food price hikes are hurting most . . .

AMY GOODMAN: For our last segment, we look at the dramatic rise in global food prices, adding a new level of danger to the crisis of world hunger. In Africa, food riots have swept across the continent, with recent protests in Burkina Faso, Cameroon, Ivory Coast, Mauritania, Senegal. In most of West Africa, the price of food has risen by 50 percent—in Sierra Leone, 300 percent. Last week, African finance ministers warned the rise in international food prices “poses significant threats to Africa’s growth, peace and security.” Other protests have been held this past week in countries like Cambodia, Indonesia, Egypt. In Haiti, at least five people have died in riots over 50 percent price hikes for rice, beans and fruit since last year. The demonstrations continued Monday outside the national palace in Port-au-Prince.

HAITIAN DEMONSTRATOR: We are protesting voluntarily. It is not for money. The parliament is responsible for all of this. All we ask for is for the government to cut down on prices of food.

This good article from the International Herald Tribune links it all: peak oil and biofuel, planterary urbanization and growth in meat consumption for middle classes, increase in food prices, especially hurting the poor, and spreading food riots across the globe.
